IMPROVEMENT IN SEEDING-MACHINES.

The Schedule referred. to in these Letters Patent and making part of thesame.

do hereby declare that the following is a full, clear,

and exact description of the construction and operation of thesamereference being had to the accompanying drawings, making apart ofthis specification, in which- Figure l is a plan, a portion of thetongue and one of the braces N having been broken away to show theconstruction of the joint that connects them.

Figure 2 is a longitudinal vertical section, a portion of one of thedrag-bars having been broken away to reveal the construction andoperation of the wedge that holds the teeth.

In this invention, the construction of the frame is greatly simplified,and better adapted for its purpose, and a novel method of holding theteeth is employed, whereby they letain their proper position whenworking in tillable soil, but yield to immovable obstacles.

In the drawings- AAare two parallel cross-beams ofthe frame, united attheir ends by metallic plates or castings B B, which furnish a bearing,b, for the axles G O, the latter being supported at their inner end byshort stout bars E E, fastened to the under edge ofthe beams.

D D are the drag-bars, supported at their forward end upon a rod, d,which extends from a lug at the lower rear corner of one plate B to asimilar lug on the other plate.

" These drag-bars are connectedv by a bar, F, lying i across their back,said bar being attached loosely to eaclrdI'ag-bal, by means of a headedpin and slot, a device well'linown in this class of machines.

Each drag-har is provided with its cultivator-tooth lGr, pivoted at thetop of its rear standard, in an open slot in the rearA end of thedrag-bar, as shown at a,

,and having its forward standard operating in connection with a wedge,w, having a curved or concave rear edge, which drops between it and thefront end of the slot, and serves to hold it so firmly that it will notturn back on its pivot in ordinary soil, but will yield withoutbreaking, when in contact with any immovable obstacles. p

Heretofore, in machines of this class, it has been generally considerednecessary to provide the frame with two stout beams, in addition 'to thebeams AA', viz, one in front, to support and brace the tongue, and onein rear, .to support the drag-bars', or the standard and lever by whichthey are raised and1 lowered.

In this machine, the necessity for such beams is obviated, and theframe, while equally strong, is'rendered lighter and smaller, bystepping the tongue M in a socket, m, xed to the front side of beam A,and bracing it on each side, by means of oblique braces or hounds N Nextending from the sides of the tongue,

just behind the team, across the upper edge of both beams A A', and to apoint nearly over the lifting-bar F, as shown in the drawings, saidlbrace-beams being bolted to the sides of the tongue, as shown at n n,and also to the cross-beams A A.

Additional metallic brace-rods I I may he employed if preferred, and therear ends of the braces N N may bemade to support a tool-box, J, whichwill be con- Y venient in case of accident in the field.

The drag-bars may all be raised and lowered at once, by means of chainsH extending from the bar F, up over segment pulleys K K, to one of whichis attached a lever, L, said apparatus being all supported by curvedstandards O O, fastened upon the b racebeams N N,.near their rear end,and projecting upward and backward, as shown in iig. 2.

lhe two (or more) segment pulleys, are firmly xed upon a rockshaft, It,and a spring-pawl and ratchet may be employed, in connection with thelever, to hold the teeth at any desired elevation.

We would call attention to the fact, that the arrangement of th beams NN, in connection with the tongue and the cross-beams A A', enables us todispense with any beam parallel to, and either in front or rear of thetwo cross-beams, for the purpose of snpporting or bracing the tongue orany other parts of the machine. This enables ns to makeV our machinelighter and more compact than any other now in use, without in theslightest diminishing its strength. It also brings the team nearer tothe body of the machine, an obvious advantage when working in a fencedfield, and it furnishes the strongest and best support for the standardsO 0, besides providing a convenient and safe place for the tool-box J.

Having tlms described our invention, v

WVhat we claim as new, and desire to secure by Letters Patent, is-.-

1. In a seeding-machine, the construction and arrangement of the tongueM and brace-beams N N, in connection with the two parallel cross-beams AA', substantially as and for the purposes set forth.

2. In connection with the described arrangement of tongue, cross-beams,and braces N N, in a seeding-machine, the arrangement of the standards OO, which, support the lifting-chains and lever, upon the rear end of thebraces, substantially as and for the purposes specified.

3. The means herein described forfasteningthe teeth G, viz, the wedge w,operating between thefront edge of the forward shank of the tooth andthe front cndof the slot in the drag-bar, substantially as and for thepurposes indicated.
